Hey guys, within the past month I have begun upgrading TM hi capas. I need help with what setup would get me a great consistent fps + accuracy? The parts I have in my gun right now are:

- PDI 6.01 inner barrel
- Nine Ball piston head
- Nine Ball enhanced floating valve spring
- Nine Ball hop up rubber
- SD POM set
- Action Enhanced floating valve
- King Arms 150% hammer/recoil spring

This setup yielded pretty good results chronoing at around 316 fps using 0.25g BBs roughly translating to 350 fps using 0.20g BBs. Still not good enough for me seeing as how some people are achieving 370-390 fps using the standard 5.1" barrel length. I have no idea how they do it.

I'm sticking with a 5.1" barrel so unfortunately using a longer barrel will not be an option. If you have any suggestions as to what would give me a more powerful and/or accurate setup that would be super. Looking forward to hearing all your AMAZING setups.

you've got a good set up. if it works well, i would leave it alone. you'll realize that after you start breaking stuff in you quest for more power.
what are you doing for mag valves?
mag temp makes a big difference and accounts for peoples (testing) variances.
nine ball piston heads have a tendancy to blow rings at higher pressure. you may want to try sd piston head.

My SD piston head's O-ring's fit with the SD nozzle is so tight that the nozzle does not move freely within the BBU. Is there another o-ring that will work with the SD piston to give optimal performance without being so tight that the nozzle won't move?
